These studies suggest that atorvastatin, at doses ranging from 10 to 80 mg per day, effectively reduces LDL-cholesterol by approximately 36% to 53%, but does not have a significant effect on HDL-cholesterol.

Atorvastatin: Lipid-Lowering Efficacy and Blood Thinning Properties
Introduction to Atorvastatin and Its Primary Use
Atorvastatin is one of the most widely prescribed statins globally, primarily used for its lipid-lowering effects. It is effective in reducing blood total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides, which are critical factors in managing cardiovascular diseases .
Lipid-Lowering Efficacy of Atorvastatin
Dose-Related Effects on Blood Lipids
Research has consistently shown that atorvastatin exhibits a linear dose-response relationship in lowering blood lipids. Studies involving over 33,000 participants have demonstrated that doses ranging from 10 to 80 mg/day can reduce LDL cholesterol by 36% to 53%. An updated review, which included nearly 39,000 participants, confirmed these findings, showing a reduction in LDL cholesterol by 37.1% to 51.7% across the same dose range. These effects are consistent regardless of the presence of cardiovascular disease.
Comparison with Other Statins
Atorvastatin's efficacy has been compared with other statins, such as rosuvastatin. While both drugs show similar dose-related effects on cholesterol and LDL cholesterol, rosuvastatin is approximately three times more potent than atorvastatin.
Gender and Genetic Factors in Efficacy
Subgroup analyses have revealed that atorvastatin's cholesterol-lowering effects are more pronounced in females compared to males. Additionally, individuals with non-familial hypercholesterolemia experience greater benefits from atorvastatin than those with familial hypercholesterolemia.
Safety and Adverse Effects
Withdrawals Due to Adverse Effects
The safety profile of atorvastatin has been evaluated in numerous trials. Short-term studies indicate that the rate of withdrawals due to adverse effects (WDAE) is not significantly different between atorvastatin and placebo groups, with a risk ratio of approximately 0.99 . However, the incidence of adverse effects remains uncertain due to the short duration of these trials and incomplete reporting in a significant number of studies .
Atorvastatin as a Blood Thinner
Lack of Evidence for Blood Thinning Properties
While atorvastatin is highly effective in lowering blood lipids, there is no substantial evidence to support its use as a blood thinner. The primary focus of atorvastatin research has been on its lipid-lowering capabilities, and no significant data suggest that it has anticoagulant or blood-thinning properties.
Conclusion
Atorvastatin is a potent lipid-lowering agent with a well-documented dose-response relationship in reducing LDL cholesterol and triglycerides. It is more effective in females and individuals with non-familial hypercholesterolemia. However, its role as a blood thinner is unsupported by current research. The safety profile of atorvastatin appears favorable in the short term, but long-term adverse effects require further investigation.
